Analyses of molecular variance (AMOVAs) based on five nuclear microsatellites of ten Swiss oak stands grouped as pure and mixed stands (Quercus petraea, Q. robur, Q. pubescens and mixed Q. petraea/robur) or pure stands only (both groupings were done on the basis of either leaf morphology or microsatellite data)

		Data basis for taxon assignment

Taxonomic assignment of stands to the respective groups follows the one given in Table 1.

d.f., degrees of freedom, SS, sums of squares.

*P < 0·05; **P < 0·01; ***P < 0·001; n.s., not significant.
